Product profile
1.ε-polylysine is a naturally produced, cationic homopolymer of 25-30 l-lysine ( due to Streptomyces albulus fermentation.), which was connected by ε-amido bond compounded by a e-amido of l-lysine and a e-carboxyl of another l-lysine.
2. ε-polylysine can greatly inhibit the growth of bacteria, yeasts and moulds bacteria, especially to the Gram+ bacteria which can't easily inhibit by others. As a good preservative, ε- PL is characterized as being high safety, water-soluble, stable at high temperatures, widely usage, non prejudice to the taste, antibacterial in neutral or subacidity conditions. Because of the stability at high temperatures, it can inhibit some heat-resistant bacillus after heat treatment and some tadpole-form noncontractile siphovirus as well.
3. ε - PL can stop small intestine fat absorption through inhibiting pancreatic lipase activities, so it can be the dietotherapy for obese patients. Besides, ε - PL also can be used in cosmetics, disinfectant or cleaner for food machinery or hutch, etc.

Hazard Identification
ε-Polylysine was found to be non-toxic at high levels in acute animal studies and was not mutagenic in bacterial reversion assays. ε-Polylysine is “Generally Recognized As Safe” (GRAS. GRN000315) by the FDA.
